Calculation ofthe β RegisterValues
The quantized β coefficient consists of two components, β0 and
β1, according to
β ≈ βquantized = β0 × 2(17 + β1)
where β0 and β1 are the register values.
Calculation of β1 is a two-step process that leads to the
calculation of β0, which is also a two-step process.
x = ceil(log2( β ))
β1 = min[31, max(0, x)]
y = round( β × 217+β1)
β0 = min[131071, max(1, y)]
Using the example value of β = 6.98672 × 105 yields
x = 13, so β1 = 13
y = 75019.3347657728, so β0 = 75019
This leads to the following quantized value, which is very close
to the desired value of 6.98672 × 105:
βquantized = 75019 × 230 ≈ 6.986688823 × 105
Calculation ofthe γRegisterValues
The quantized γ coefficient consists of two components, γ0 and
γ1, according to
γ ≈ γquantized = γ0 × 2(17 + γ1)
where γ0 and γ1 are the register values.
Calculation of γ1 is a two-step process that leads to the
calculation of γ0, which is also a two-step process.
x = ceil(log2( γ ))
y1 = min[31, max(0, x)]
y = round( γ × 217+γ1)
γ0 = min[131071, max(1, y)]
Using the example value of γ = 7.50373 × 105 yields
x = 13, so γ1 = 13
y = 80570.6873700352, so γ0 = 80571
This leads to the following quantized value, which is very close
to the desired value of 7.50373 × 105:
γquantized = 80571 × 230 ≈ 7.503759116 × 105
Calculation ofthe δRegisterValues
The quantized δ coefficient consists of two components, δ0 and
δ1, according to
δ ≈ δquantized = δ0 × 2(15 +δ1)
where δ0 and δ1 are the register values.
Calculation of δ1 is a two-step process that leads to the
calculation of δ0, which is also a two-step process.
x = ceil(log2(δ))
δ1 = min[31, max(0, x)]
y = round(δ × 215+ δ1)
δ0 = min[32767, max(1, y)]
Using the example value of δ = 0.002015399, the preceding
formulas yield
x = 8, so δ1 = 8
y = 16906.392174592, so δ0 = 16906
This leads to the following quantized value, which is very close
to the desired value of 0.002015399:
δquantized = 16906 × 223 ≈ 0.002015352249
